HEAD.

SPECIFICATION forming part of Letters Patent No. 357,750, dated February15, 1887.

Application filed April 19, 1886. Serial No. 199,419. (No model.)

To all whom t may concern:

Be it known that I, JOHN Q. ADAMs, a citizen of the United States,residing at Marseilles, in the county of La Salle and State of Illinois,have invented a certain new and useful Improvement in Pnmp- Heads, whichis fully set forth in the following specification,

reference beinghad to the accompanying drawings, in which- Figure lrepresents a side elevation of a pump-head embodying my invention, Fig.2, a front elevation of the same; Fig. 3, a vertical section of the sametaken on the line man, Fig. l; Fig. 4, a plan section ofthe same takenon the line y y, Fig. 3; Fig. 5, a similar section taken on the linezz,Fig. 3; and Fig. 6, asimilar section taken on the linen o, Fig. 3.

Figs. I and 2 of the vdrawings are on one scale, and Figs. 3 and 4 onthe saine scale, but enlarged, and Figs. 5 and 6 on the same scale,

` but still further enlarged.

My invention relates to pumps which are designed to be operated eitherby hand or by a windmill, or other power adapted to give the necessaryvertical reciprooation to the piston-rod.

The invention relates especially to the mode of mounting the pump-handleupon the head and the devices by which it is connected to the pistonsrodwhenever it is desired to work the pump by hand.

I will proceed to describein detail one way in which I have practicallycarried ont myinvention, and will then point out definitely in theclaims the particular improvements which I believe to be new and wish toprotect by Letters Patent.

In the drawings, A represents a pump-head, which may be of any ordinaryconstruction. It is surmounted by a close-fitting cap, B,which isprovided with an opening, b, of any angular or irregular shape tocorrespond with the shape of the piston-rod C, which passes down throughthis opening in the cap. The cap is fastened to the pump-head by anysuitable means, set-screws b being shown 'in the drawings for thispurpose. A standard,D, rises from the cap at one side, being preferablycast in one piece therewith, which at its upper end is bent or turnedinward and is provided with an opening, d, corresponding to the openingin the cap below, and consequently conforming to the shape of thepistonrod,which passes up through this arm of the standard. The

standard is slotted centrally nearly from top r to bottom, and each sidebranch has a lug or ear, d, projecting outward from the standard, theselugs being joined at their ends by a crossbar, di, thereby forming akind of loop at the side of the standard, but preferably in one piecewith the latter. A link, E, is arranged within this loop and is pivotedat its lower end to the standard by any suitable device. the drawingsapivot-pin, e, is shown, passing through the sides of the standard andthe link. The other end of the link is pivoted to the handie F by anyordinary means, and the link itself is secured to the standard in a txedposition by a, pin, G, which passes through holes g in the upper portionof the side lugs and a hole, e, toward thegupper or outer end of' thelink. These upper holesl in the side lugs of the standard are made somedistance inside of the crossbar of the loop, to permit the link to swingbackward andl outward when the pin G is removed, as and for the purposehereinafter described.

The pistorrrod C is provided with a box, H, below the upper end of thestandard. If the piston-rod were large enough,this box could be providedby slotting the rod; but as the ordinary piston-rod is not large enoughfor this purpose I construct a box from side pieces, h, bent angularly,as shown in Fig. 1 of the drawings, which are fastened at theirrespective ends to sections of the piston-rod, the latter being severedat this point for the purpose. The box therefore constitutes a part ofthe piston-rod; but as its sides are extended outward by means of theangular bends, as shown in Fig. l ofthe drawings, it is obvious that anopening is provided between them which extends through from side to sideof the box, being open on both faces.

IVhen the handle F is arranged in working position by fastening the linkE to the-standard by means of the pin G, its inner end is intended toenter the box H in the piston-rod loosely. This end of the handle isprovided with small rollers f, which fit in the box, be ing arranged oneach side of the handle, preferably as shown in the drawings, andadapted IOO to about fill thebox. handle works upon a fixed pivot andthe piston moves in a straight line there must be provision made at thejoint between the piston-rod and the handle for the changing position ofthe inner end of the handle as it moves through its are of motion. Thisprovision is found in the loose `joint-connection just described; for,obviously, as the handle is vibrated and the piston-rod moved up anddown the inner end of the handle will move freely back and forth withinthe box, the rollers facilitating this action by overcoming thefriction, and there will heno binding in the working of the pump bymeans ofthe handle. A holeis provided in the upper end of thepiston-rod, by means of which it may be attached to the connecting-rodof a windmill whenever it is desired to operate the pump by this power.Any' other ordinary device for making this connection may be employed,as the means adopted for this purpose constitutes no part of my presentinvention.

Vhen the pump is to be worked by-a windmill or any other power,it is ofcourse desira; ble to disconnect the handle from the pistonrod, so as toavoid the useless vibration of the handle. rlhis is readily effected inmy invention by simply removing the pin G, when,ob viously,the handlemay be pulled outward until it is disconnected from the pistonrod, thelink E swinging outward within its loop to permit this action, andfinally resting upon the cross-bar at the outer portion of the loop.When lit is desired to work the pump by the handle agaimit is onlyVnecessary to throw the link up and insert theinnerend ofthe handle inthe box of the piston-rod and fasten the link to the standard 'by againinserting the pin G.

It will be seen from this description that the connection between thehandle and the piston-rod is an entirely loose one, requiring noseparate piece to fasten the two together. Connection and disconnectionbetween the two parts is ecected simply by swinging the link on whichthe handle is mounted, and the latter is fastened in place for workingthe pump by the handle by inserting the pin G in the proper holes, andunfastened to permitY the handle to be pulled away from the piston-rodby simply removing the same pin. When the pump is to be operated by thehandle, it will be seen that the pivot of the latter is fixed, for thelink on which it is mounted is then made fast, so that it cannot swing.

I do not wish to be understood as limiting- It is obvious that as themyself to the precise details of construction herein shown anddescribed. The handle may be differently mounted and differentlyconnected to the piston-rod and yet the main features of my improvementretained, which are the support of the handle upon the standard by meanswhich provide a fixed pivot for the handle in working position, and atthe same time permit the latter to be pulled outward to disconnect itfrom the piston-rod, and a loose ioint or connection between the handleand the piston-rod, whereby these two parts may beconnected anddisconnected without the interposition of any additional device, and thehandle is permitted to move transversely to the rod. Other parts of thestructure may also be changed in details without departing from the mainfeatures of my improvement.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

l. rlhe pump-handle, in combination with a pivotal support therefor,adjustable at its swinging end, and a fastening device whereby saidsupport may be secured in a iixed and rigid working position,substantially as and for the purposes specified.

2. The piston-rod provided with a device for receiving the end of thehandle, in combination with the pump-handle applied to the rod, but notattached thereto, an adjustable pivotalsupport for saidhandle, and afastening device whereby said support may be secured in a fixed workingposition,substantially as specified.

3. The pump piston-rod C, provided with box H, in combination with thehandle F, adjustable in the direction of its length, provided at itsinner end with rollers f, arranged to enter and tit the box H, and theadjustable pivoted link E, substantially as specified. 4. Thepump-handle F, in combination with the pivoted link E, the standard D,and the fastening-pin G, substantially as specified. a

5. The standard D, provided with the side loop, d d2, in combinationwith the pump-handle F, pivoted 'link E, and fasteningpin G,substantially as specified.

6. The pump piston-rod C, provided with the box H, in combination withthe standard D, pump-handle F, pivoted link E, and fastening device G,substantially as specified.
